This invention relates primarily to machines for operating upon soles.The invention' is illustrated as embodied in a machine designed forproviding an insole with positioning surfacesto be utilized inshoemaking operations.

Ina co-pending application of thepresen't' applicant filed February 12,1925, now Letters Patent No.'1',674 ,O60, granted June 19,1928, Iisdisclosed a method and, a machine relating to the lasting of the toeoffa shoe, a characteristic of which is that'a last andinsole are eachprovided with a plurality'ofpositioning sur-;

' faces in spaced locations, preferably provided by positioning holes,by'theuse'of which-the v insole, the last and the shoe upper materials,

which are to be shaped thereon, may be posi-- Y tio'ned quickly andaccurately in relation'to lasting devices of a lastingmachine j'JAnlmportant object of'the present inveni tion is t o "provide amachine-particularly adapted for. use in preparing such an insole whichpositioning' holes may be formed in; an insole in definite,predetermined relation! to the edge contour of the insole and also, inthe case of a welt insole, .to'the insole rib and preferably inrelatively close proximity to the rib.

' To this end, the invention, inone aspect, comprises an improvedmachine for operating I described. In the particular embodiment of 5 theinventionherein illustrated,"themachine is. constructed and arranged toprovide an in sole with three positioning, holes in predetermined,spaced relation to thecontourjof I the insole and adapted tobe used incarrying outthe method claimed in Letters PatentNo.1,674,060hereinbefore referred to but, in some aspects, the invention isnot limited to such embodiment and use.

The invention will now be described indethe treadle mechanism notillustrated);

may be of any known-or suitable construction;

The other arms24 'of'the bell cranks areconnected by a tensionspring 26 which tends to'move'the free e'nds ofthegages 16 toward each other 1 but their movement of approach islimited by and, more specifically, a machine by the use'of theengagement of an adjustable screw stop 28 w th a lug 30 formed asanextension of one ofthe bell cranks 20;? Another pair ofsidegages336-are likewise-provided with studs 38 pivoted in the-solefsupportand connected toof approach stop'aa.

In a machine r punching in an insole a plurality of positioning holesin predetermined relation to the insole contour, the combination of asole support, a power shaft, a plunge'r,-actuating connections betweensaid shaft and said plunger, a punch holder and a yielding strippercarried by the plunger, 1 three punches mounted on the holder and solocated as to form positioning holes in the Y insole, one near the toeend thereof and two rearwardly therefrom and near the sole coni ,tour,means for maintalnlng said plunger,

holder and punches in predetermined angular relation to each other andto the sole support, and yieldingly pressed gaging devices forcontacting with the curvilinear contour of the toe portion of the insoleat'least at four separatedpoints and thereby locating the insole on thesupport in predetermined position relatively to the punches. 5 V Intestimony whereof I have signed my name to this specification.
